At-the end of. theover-wiping operation, as previously explained, the driver; 40 isreleased to the action of its operating spring forthe insertion of astaple which is driven through the over-wiped margin of the upper andthrough the insole, theends ofits legs being clinched on the iron plateon the bottom of the last. The means for feeding the wire to form thestaples may be i and preferably is substantiallythe same as that fullyshown and described in'Letters PatentNo. 1,731,853 granted October 15,1929 upon anapplication. of George Goddu and need not be describedherein in detail. Briefly stated, the wire is led from a reel and idler(notshowml down wardly between feed wheels I58 and I60 (Fig. 3)

and thence through a flexible tube I62 and a sleeve or quill 154 (Fig.'1) to the wire-guiding nozzle 14. The feed wheel 158 is operated by aratchet and pawl mechanism I66 (Fig. 3) through an adjustable link I68and a bell-crank lever I10 provided with a roll I12 (Figs. 1 andj3) en-:1 I gaged by a cam wheel I14 fast on a cam shaft wheel I14 (Fig. 3).Fast, on the cam shaft I16 is a bevel gear I88 that meshes witha'smaller bevel gear I90 secured to the lower end of a'vertical shaftI82 which is rotatably mounted in a bearing in the head 26 and at itsupper end'is geared to the main camshaft 12'of the machine. Theconstruction is such that the cam shaft I18 is rotated through 180 forone complete move ment of rotation of the main cam shaft 12 in eachcycle of operations of the machine, thecam I86 being so shaped that thebell-crank lever I10 is first swung in a clockwise direction (Fig. 3) bythe action of the spring I64 on the rock shaft I82 substantially at thebeginning of each cycle of operations of the machine and before the mainslide 38 begins its forward movement, after which'the bell-crank lever.I10 sis swung reversely by the cam I86 to its initial starting Itwill beunderstood that clockwise will act through the ratchet and pawl deviceI66 to rotate the feed wheel I58to feed a length of wire between theinsidepand outside formers of the machine, v

In the machine herein shown there is provided an adjustablestoppillustrated as :ascrew I94, which acts by engagement with an armI98 on the bell-crank lever I10 to limit the extent ofclockabove-mentioned bracket 88.

wise swinging movement 'of the bell-crank lever (Fig. 3) undertheinfluence of the spring I84, thus stopping the operation of the feedwheel I58 when a predetermined length of wire is fed into position to beacted upon by the inside and outside formers of the machine. Itgwill beunderstood that by varying the positionof the adjustable stop screw I84theleiitent of clockwise'swingingmovement imparted to the bell-cranklever I18 may be varied as'desired to vary the length of the wire fedtoform a staple. As herein shown, the adjustable screw I84 is carried by aplunger I98 which is vertically movable in a recess in the bracket. I18,a lock nut 288'being provided for holding the screw I94 inadjustedposition relatively to the plunger. The plunger I98 rests on theperipheral edge face 282. of a segment 204 that is pinned totheleft-hand end portion of a shaft 288 which is mounted in a bearing inthe The peripheral edge face 282 of the segment 284 is eccentric to theaxis of the shaft 288 (Fig, l) and, in order that the segment may berotated quickly to vary the heightwise pcsitionlof the plunger I98 and nthe stop screw I94, and thus torvarythe length of wire fed to form thestaples and consequently the lengthsof the staples, for operating upondifferent portions of-the same shoe, there is fastto the right-handend-portion of the shaft 206 a device comprising a hand lever-288 (Figs.2 and 3). Itwill be understood that/a finer adjustmentof the lengthofwire fed may be made by adjustment of 'thescrew I94 relatively to theplunger I98. For determining-the properlimits of movement of thehandlever 288 in opposite irections to vary the position of theadjustable stop I94 and thereby to control the lengths of feed of the.wire in accordance with the desired lengths ofrthe staples to be formedin operating upon different portions of the same shoe, there areprovided stops 2I4, 2I5 (Fig. 2) adjustably secured in a curved guideway2E6 formed in a bracket member 2I8 which is secured to the bracket 89 byscrews 2I9. a 7

As previously pointed out, the stationary cutter or' wire-guiding nozzle14 (Figs. 3 and 10) is carried by a bracket 16 on which is slidablymounted the movable cutter 84. 'The bracket 16 isadjustable laterally ofthe slide 88 on the guideway 18 (Figs. 1 and 4) formed on the bracket 89and pivotally connected to the bracket is a lever 220 (Fig. 4) providedwith an upwardly extending arm which is, forked to straddle a pin 222projecting from the bracket 16 and with a downwardly extending armcarrying a pin 224. The

pin 224 is arranged to extendinto a peripheral cam slot 226 formed inthe segment 284, The shape of the cam slot 226 is such that, in allpositions of adjustment of the segment 284 and the adjustable stop I94to vary the length of wire fed to form the staples, the stationary andmovable cutters 14 and- 84 will be positioned in proper relation to theinside and outside formers of the machine to insure that the legs ofeach staple when formed from each severed piece of wire will be ofsubstantially the same length.

In the use of the illustrated machine for 1asting shoes of thethrough-and-through sewed type, it is contemplated that staples will beformed of sufficient length to insure that the ends of their legs willpenetrate entirely through the insole but only far enough to cause aslight clinching of the ends of the legs'on the metal plate P (Fig. 15)on the bottom of the last in the driving operation, thus insuringagainst any danger of :injury to theifoot of the wearer of :the shoesuch as' mig'ht occur if excessively long r-staple's im properlyclinchedwere used. Since-the upper materials at the toe and heel endsare ofgreat-er thickness than along the sides of the shank and ballportions or" the shoe because .0f.-the. added thickness of the toestiffener-around'the'toe end and the counter around the heel end, :itwill be necessary for the operator to vary the adjusted position of thestop 5-94 so-that the desired lengths of staples will be formedforoperating upon these differentlportions of the shoe. By adjustment-ofthe stops 2M and 215 alon'gthe curved guideway M6 the lengths of the'staplesjformed for use'inoperating upon diiferent portions of .theshoe'may be varied and determined as desired In the illustratedconstruction, means-is ,pro-

Asshown particularly-in Fig.2, there is pivotally connected to the,edge'gage 28 arc-d 2-2 that extends rearwardly througha stud-231i whichis pivotally connected to the device-hi8. Mounted on the rod 228 areadjustable collars 3-32 ,13'4 that maybe secured in adjusted position onthe nod by set screws The construction is such'that as the edge gage 23is moved'forwardlytoits operative position the collar 232 will act byengagement initial inoperative position would cause-thead justablecollar on the rod' 223 to en-gagethe stud 233 and to swing the deviceifi8j reversely into the position determined by the adjustable stop 253-. As previously mentioned, it will be understood that the stops 2l4vand;2i 5 willbe adjusted along the curved guideway ZlSso as t o varythe adjusted position of the 'stop-screw l94 .to control the lengths offeedofrthe wire in accordance with the desired lengthsofthe staples tobe formedin operating upon the different portions of the shoe bottom.Since it is; necessary for the operator to move the edge gage .23forwardly to its operative position in lasting around the toeend of theshoe and at-the. oppositesides thereofin locations at or rearwardly ofits heel breast line,wand to movethe edge gage toiits'rearwardinoperative positionin lasting along the sides of the shank and ballportions of tho s hoe,

The shape non through an angle of 90of the other half of the cam 28B is such that in this next cycle ofoperations of the machine, after the feeding operation and beforet-hesevering operation, the lever 2'12 is swung'in a direction oppositeto the direction of its first swinging movement in the last precedingcycle, so that the beveled'end 282 of the wire will have been rotatedthrough 180 about the longitudinal axis of the wire before the nextpiece is severed (Fig. 12). As the fed-in portion of Wire is thensevered in response to the forward movement of the slide 38, the angularfaces on its opposite ends will be located on the same side of the wire.Thereafter, the cam 280 will swing thelever 2E2 reversely to its initialstarting position, thus causing the wire to be rotated through 90toremovethe twistin the wire after the wire-severingoperation. From theabove description it will be evident that the wire W is turned 180 firstin one direction between successive wirecutting operations and then inthe opposite direction before the next. wire-cutting operation to causethe angularfaces on the'opposite ends of each severed piece of wire tobe located in the desired relation, 90 of each turning .movementoccurring'after each severing operation so that the Wire is in untwistedcondition each time it is fed. Accordingly, as the wire is fed it offersno resistance to the action of the feed rolls I58 and Manor is there anytendency for the wire -to rotate the quill 164 and bushing 265, such aswould occur if the wire were fed in a twisted condition. The feeding andturning movements imparted to the wire during two successive cycles ofoperation of the machine are illustrateddiagrammatically. in Figs. 11'to 14 inclusive. As shown particularly in Figs. 12 and 14, the passage284 for the wire W in the nozzle 14 is-angular in cross section and issufficiently large to permit 'the wire to be turned therein, twosurfaces of the passage acting by engagement with adjacent faces of thewire tosupport it during the wirecutting operation. i

In the illustrated machine each staple is formed with its cross-barextending laterally of the slide through the same angle in the oppositedirection in' the next cycle of, operations, said turning means beingsoconstructed as to turn the materialreversely to ';its starting positionin each cycle after the severing operation.
